Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring grinding, in particular to a grinding tool for the end surface of a bearing ring with a complex supporting surface. Background Art

[0002] The bearing is composed of an outer ring, an inner ring, rolling elements and a cage, and plays the role of supporting the mechanical rotating body. The outer ring and inner ring in the bearing are collectively called bearing rings. The end face of the bearing ring plays the role of installation reference and processing reference surface. Therefore, its end face accuracy and wear resistance directly affect the final quality of the bearing.

[0003] Traditionally, large-diameter, thin-walled bearing ring end face grinding uses a weak magnetic attraction and clamping tooling or a non-magnetic attraction and clamping tooling method, which has low processing efficiency and high requirements on operator skills.

[0004] Chinese patent CN116512029A discloses an auxiliary tooling for grinding the end face of a bearing ring and a method of using the auxiliary tooling, comprising: a plurality of independent units of the same specification, which are combined as an integral unit to be installed with a workpiece; the end face of one side of the workpiece on which the integral unit is installed contacts the plane of the bearing processing grinder; and then the workpiece is fastened by the magnetic force of the plane magnetic disk of the grinder, thereby solving the defects existing in the process of grinding the end face of the outer ring of this type of workpiece, providing a new processing method for special-shaped products, and achieving a new breakthrough in the grinding method; the auxiliary tooling has a simple structural design, and overcomes the defects of the workpiece not being able to be adsorbed due to too small magnetic force during grinding, and the defect of excessive flatness of the workpiece after grinding caused by too large magnetic force; the tooling will not move or tilt during the grinding process of the workpiece, and the accuracy and surface quality after grinding are guaranteed.

[0005] However, this technical solution can only process one end face of the ring at a time, and the other end face of the ring needs to be processed by flipping and other operations. The operation is cumbersome, inconvenient to use, and has low work efficiency. In addition, when it is necessary to grind the end face of a large-diameter thin-walled bearing ring, it is very likely that the bearing ring will be unstable due to insufficient magnetic force, and it may be offset, and the fixing effect is not good, resulting in low grinding efficiency and poor precision. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies in the prior art and provide a tool for grinding the end faces of bearing rings with complex supporting surfaces. By arranging two sets of movable supporting components on a feed plate and fixing them in contact with the bearing rings, the function of quickly and stably placing the bearing rings on a horizontal double-end surface grinder for processing is achieved, thereby solving the problems of double-end surface grinding support of curved outer surface bearing rings in the prior art as well as the problems of inconvenient operation and low work efficiency.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A tool for grinding the end face of a bearing ring with a complex supporting surface comprises a feed plate, on which a placing station is arranged, and along the circumferential direction of the placing station are two groups of supporting components for abutting and sliding against the bearing ring to be processed.

[0009] Preferably, the placement station is provided with a loading hole adapted for the bearing ring to be processed.

[0010] Preferably, a slide groove matched with the supporting assembly is provided on the feeding plate, and an extension line of the slide groove passes through the center line of the placement station.

[0011] Preferably, the support assembly comprises: a support block slidably connected to the feed plate and a support head rotatably connected to one end of the support block.

[0012] Preferably, the support head comprises:

[0013] a bearing, rotatably connected to the top end of the support block, and the bearing is horizontally arranged; and

[0014] The spherical sleeve is arranged on the outer periphery of the bearing, and the spherical sleeve is arranged opposite to the bearing ring.

[0015] Preferably, the chute is communicated with the charging hole.

[0016] Preferably, the support block and the feeding plate are fixedly connected via a plurality of fasteners.

[0017] Preferably, grooves are provided on both sides of the support block, and the fastener passes through the grooves and is fixedly connected to the fixing holes on the slide slot.

[0018] Preferably, the bearing is rotatably connected to the support block via a rotating member.

[0019] Preferably, a mounting groove adapted to the supported head is provided at the top of the support block.

[0020] The beneficial effects of the utility model are:

[0021] (1) The utility model supports and fixes the bearing ring to be processed by two groups of supporting components, and the spherical sleeve on the supporting head abuts against the bearing ring to be processed to form a two-point contact support form. There is no need to fix the bearing ring separately, so that the bearing ring is more stable and firm and will not easily shift, thereby ensuring the accuracy of end face grinding. In addition, the tooling can process the two end faces of the bearing ring at the same time, without requiring excessive manual operation, saving time and effort, and improving work efficiency.

[0022] (2) The utility model is movably connected to the feed plate through the support block, so that the spherical sleeve can move freely, that is, it can be adjusted accordingly according to the actual size of the bearing ring. In other words, the tooling can be used for grinding bearing rings of different sizes, thereby expanding the scope of application of the grinder.

[0023] (3) The utility model adopts a spherical outer surface of a rotatable support head by designing the structural form of the support head, which can meet the support requirements of various curved surface parts and significantly expand the processing range of the horizontal double-end surface grinder.

[0024] (4) The utility model uses a bearing and a spherical sleeve to limit the bearing ring to be processed, and then combines it with a slidable support block, so that the overall structure of the tooling is simple and easy to disassemble and assemble.

[0025] In summary, the utility model can use the tooling of the utility model to support the bearing rings with complex surfaces, and realize the requirement of end surface processing thereof by a horizontal double-end surface grinder, which greatly improves the production and processing efficiency while improving the bearing processing accuracy and saving processing costs.

[0035] Example

[0036] like Figure 1-6 As shown, this embodiment provides a tool for grinding the end face of a bearing ring with a complex support surface, comprising: a feed plate 1, a placement station 11 is arranged on the feed plate 1, and two groups of support components 3 are arranged along the circumferential direction of the placement station 11 for abutting and sliding against the bearing ring 2 to be processed, and the position of the support component 3 can be adjusted accordingly according to the actual size of the bearing ring 2 to meet the processing of bearing rings 2 with different diameters. The tool is mainly suitable for horizontal double-end surface grinders, that is, the end face of the bearing ring 2 is in a vertical state during processing, and the bearing ring 2 does not need to be fixed separately. It only needs to be directly placed on the support head 32, which ensures the position accuracy of the bearing ring 2 during the grinding process, and thus ensures the processing accuracy of the end face grinding, and the entire processing process is simple to operate, easy to use, and has high work efficiency.

[0037] Among them, the placement station 11 is provided with a loading hole 111 suitable for the bearing ring to be processed, and the bearing ring 2 is installed in the loading hole 111. The loading hole 111 is used to limit the position of the bearing ring 2 to facilitate the processing and grinding of the bearing ring 2. The placement space 11 has a large space to accommodate parts, and the parts can be taken and placed conveniently and quickly.

[0038] At the same time, the feed plate 1 is provided with a slide groove 12 adapted to the support assembly 3, and the extension line of the slide groove 12 passes through the center line of the placement station 11, and the support block 31 is correspondingly arranged in the slide groove 12. The slide grooves 12 are preferably two, and are arranged at a certain angle to each other (i.e., forming a support angle), and are symmetrically arranged on both sides below the loading hole 111. The spherical generatrix of the two spherical sleeves 322 and the supported curved surface of the bearing ring 2 respectively form a two-point contact support form, and the support block 31 is fastened after the appropriate position of the bearing ring 2 is determined by a magnetic meter stand. After the adjustment is completed, the bearing ring 2 is directly placed on the two supporting heads 32, and the bearing ring 2 is lifted by the two supporting heads 32. The feeding plate 1 carries the bearing ring 2 and is fed into the gap between the two grinding heads of the horizontal double-end surface grinder in a manner perpendicular to the ground plane. The two grinding planes of the bearing ring 2 are both perpendicular to the ground plane and can be ground at the same time. After the two supporting heads 32 are adjusted, the bearing ring 2 to be ground is taken and directly placed on the two supporting heads 32 without the need to be fixed separately. The supporting method is similar to holding up the outer circle of a ring with both hands. It has a simple structure and is easy to disassemble and assemble.

[0039] In this embodiment, the support assembly 3 includes: a support block 31 slidably connected to the feed plate 1 and a support head 32 rotatably connected to one end of the support block 31. By moving the support block 31, one end face of the support head 32 is abutted against the end face of the bearing ring 2 to be processed on the feed plate 1 and then fixed.

[0040] In this embodiment, the support head 32 includes: a bearing 321 rotatably connected to the top of the support block 31 and a spherical sleeve 322 arranged on the outer periphery of the bearing 321, and the spherical sleeve 322 is arranged opposite to the bearing ring 2, so that the spherical generatrix of the spherical sleeve 322 and the supported curved surface of the bearing ring 2 respectively form a two-point contact support form, which determines the position of the bearing ring 2 and ensures that the position of the bearing ring 2 will not shift, making the bearing ring 2 more stable and ensuring its processing accuracy. The double-point support structure eliminates the need to tighten the parts to be processed, and the auxiliary time for clamping the parts can be ignored. The processing efficiency of the parts is increased by more than 6 times compared with the traditional method.

[0041] In this embodiment, the slide groove 12 is connected with the loading hole 111, so that the slide groove 12 can directly move and approach the bearing ring 2, and its structure is simple and easy to operate.

[0042] In this embodiment, the support block 31 and the feed plate 1 are fixedly connected by a plurality of fasteners 311, preferably two fasteners 311, which are correspondingly installed in the groove 312, so that the support block 31 is more stable and firm, thereby ensuring that the bearing ring 2 is more stable during processing, can be accurately ground, and ensures the processing accuracy of the bearing ring 2.

[0043] In this embodiment, grooves 312 are provided on both sides of the support block 31, and the fastener 311 passes through the groove 312 and is fixedly connected to the fixing hole 13 on the slide groove 12. The fastener 311 is preferably a bolt, which has good fixing effect, simple operation, and convenient disassembly and assembly. A plurality of evenly distributed fixing holes 13 are provided in the slide groove 12, so that the fastener 311 can be fixed in the corresponding fixing hole 13 according to the different sizes of the bearing ring 2, which is easy to use.

[0044] Of course, the bearing 321 is rotatably connected to the support block 31 through the rotating member 323, and the rotating member 323 provides power and drives the bearing 321 to rotate, thereby driving the spherical sleeve 322 to rotate. The rotating member 323 is preferably a supporting shaft because it saves materials, can reduce weight, and reduces the cost of use.

[0045] In addition, a mounting groove 313 adapted to the supporting head 32 is provided at the top of the supporting block 31, that is, the internal dimension of the mounting groove 313 is larger than the external dimension of the supporting head 32, and it is only necessary to ensure that the mounting groove 313 does not affect the normal rotation of the supporting head 32.

[0046] The working process of this embodiment is: first use a magnetic meter to determine the best processing position of the bearing ring 2, and then move the support block 31 to the corresponding position according to the position, that is, move the support head 32 to the specified position, and then lock the fastener 311 to fix the support block 31 on the feed plate 1. After the operation is completed, place the bearing ring 2 to be processed in the loading hole 111 of the feed plate 1, and the bearing ring 2 directly rests on the support head 32. Finally, send the bearing ring 2 into the gap between the two grinding heads of the horizontal double-end face grinder in a manner perpendicular to the ground plane for end face grinding.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
